Blender Version
Broken: version: 2.81 (sub 16), branch: master, commit date: 2019-12-04 11:32, hash: rBf1aa4d18d49d
Worked: (optional)

Short description of error
If you are using Look Dev display mode and either already have, or try to create, a secondary UV set on an object, the second UV set will not display in the UV Editor. If you toggle back to Object mode, switch to Solid shading mode, and then back into Edit mode, the UV's will display.

Exact steps for others to reproduce the error

  1. Open the .blend file
  2. If not in Look Dev mode, switch to Look Dev mode
  3. Tab into Edit mode. Make sure all polys are selected. In the UV editor, switch back and forth between UVMap_1 and UVMap_2 - note that UVMap_2 seems blank.
  4. Tab back into Object mode. Change viewport display to Solid mode.
  5. Tab back into Edit mode - with all polys selected, notice how UVMap_1 and UVMap_2 display as expected.

(I actually discovered this working in Blender 2.82 - but realized it was also in 2.81 - so reported it in 2.81

Able to reproduce. You don't need to switch to object mode, I was able to fix this just by selecting the UVMap_1 and UVMap_2 again.
